I collected these special edition tokens about 20yrs ago. First time they've been out of there cases. The silver in the middle is 1/2oz .999 pure silver. I searched to see if they are of any value. The age of the coins don't add value. There worth ten bucks at a casino or about nine bucks in sliver value. A collector I saw wont' sale them under fifteen bucks. I'll put them away for another 20yrs...Lol.
